I recently updated and replaced older repositories from my GitHub account that were hand made modular alerts to send search results to other Splunk instances. The first one sends the search results to a Splunk HTTP Event Collector receiver. The second one came from our Splunk 2016 .conf talk on KVStore. It was useful for sending search results (typically an inputlookup of a table) to a remote KVStore lookup table.
This is useful for taking search results and sending to another Splunk instance using HEC. If you chose JSON mode it will send the results as a JSON payload of all the fields after stripping any hidden fields. Hidden fields start with an underscore. RAW mode is a new option which takes the _raw field and sends ONLY that field to the remote HEC receiver.
This has been completely redone. I have submitted it to Splunkbase, but for the moment you can get it from my GitHub repository: TA-SyncKVStore
Originally it only sent search results to a remote KVStore. Now it also has two modular inputs. The first pulls a remote KVStore collection (table) and puts it into a local KVStore collection. The second pulls the remote KVStore collection but indexes it locally in JSON format. It will strip the hidden fields before forming the JSON payload to index. You are responsible for making sure all the appropriate and matching KVStore collections exist.
If you look in the code you will notice an unusual hybrid of the Splunk SDK for Python to handle KVStore actions and my own python class for batch saving the data to the collection. I could not get the batch_save method from the SDK to work at all. My own class already existed and was threaded for performance from my old version of the modular input so I just used the SDK to clear data if you wanted a replace option and then my own code for saving the new or updated data.
I rebuilt both of these TAs using the awesome Splunk Add-on Builder. This makes it easy in the SyncKVStore TA to store the credentials in the internal Splunk encrypted storage. One comment to update on the previous post on credential storage. The Add-on Builder was recently updated and now gives much better multiple credential management with a “global account” pull down selector you can use in your inputs and alert actions.
